    Exclamation Calibration Summary Checksum invalid but disabled

    At the completion of the calibration the following segments were displayed as either checksum valid but disabled or invalid and disabled:
    Calibration Verification - Checksum invalid but disabled
    Internal Flash - Checksum valid but disabled
    External Flash - Checksum valid but disabled

    Where do I go from here?

    06 Cummins. I found a post from 6 months ago where it was recommended to get a fresh copy of the base stock file.

    That's the Calibration number. Your original stock file should be one of those. Either ending in 5553 or 5853

    Your Welcome, Don't forget to change the VIN number within the stock tune file that you end up using!

    Where do I change the VIN number? Would I need to make the edit within EFILive V7.5?
